So does this just mean that I can't view both at once?
I should still be able to switch between one and the other, shouldn't I?
In xawtv for example there's a setting to select the video input. It
either says "webcam" or "tv card" depending on whether I've got the
webcam plugged in, but it doesn't give me the option to switch between
the two.

I would have thought that it was something like /dev/video0 was the tv
card and /dev/video1 was the webcam and /dev/video was a symlink to
whichever of these was currently being used. But this doesn't seem to
work.

Paul.
